Introduction
This manual covers the operation of internal com-
bustion powered models of the AB-46 Articulated
Boom. This manual must be stored on the machine
at all times.
Pre-Operation and Safety
Inspection
Carefully read, understand and follow all safety
rules, labels, and operating instructions, then
perform the following steps each day before use.
Perform a complete visual inspection of the entire
unit prior to operating. Check the following areas for
discrepancies:
1. Open panels and check hydraulic components /
hoses for damage or leaks. Check electrical compo-
nents / wiring for damage or loose connections.
2. Inspect chassis, axles, hubs, and steering
linkage for damage, deformation, buckled paint,
loose or missing hardware, and cracked welds.
3. Check tires for damage, punctures, and inflation;
tire pressure must be 65 psi.
4. Check all hoses / cables for wear.
5. Inspect elevating assembly for damage, defor-
mation, buckled paint, loose or missing
hardware, and cracked welds.
6. Inspect platform and guardrails for damage,
deformation, buckled paint, loose or missing
hardware, and cracked welds. Insure that gate
operates freely and latches securely.
7. Check Hydraulic fluid level with platform fully
lowered.
8. Check battery fluid level (see battery mainte-
nance, page 8).
9. Check fuel level, add fuel if necessary (see
fueling, page 8).
10.Ensure that radiator is cold, check coolant level.
Add if necessary.
NEVER remove the cap from a hot radiator.
Hot coolant can cause severe burns.
SYSTEM FUNCTION INSPECTION
Note: Refer to figures 1 and 2 for chassis and
platform control locations.
1. Before performing the following tests, check area
around machine and overhead for obstructions,
holes, drop-offs, and debris.
2. Turn chassis key switch to chassis, and turn on
(rotate clockwise) emergency stop switches at
the chassis control panel and at the platform
control panel.
3. Press the engine start button to crank the en-
gine; release when engine starts. If engine is
cold: press and hold the choke button while
starting gasoline / propane models; press the
glow plug button and hold for six seconds prior to
starting diesel models.
4. Push in the chassis emergency stop button
engine should stop. Repeat for platform emer-
gency stop button. Return both emergency stop
buttons to the on position, and start engine.
5. Operate each function switch to raise / lower,
extend / retract, rotate left / right, each section of
the elevating assembly and observe the opera-
tion of the machine. All functions should operate
through full cycle smoothly.
6. Turn chassis key switch to platform.
7. Mount the platform, close and latch the gate, and
attach approved fall restraint to designated platform
anchorage point. Attach only one fall restraint to
each point.
8. Start the engine.
9. Without depressing the foot switch, move the
drive control handle, machine should not function.
10.Depress the foot switch and move the drive
control handle forward and reverse. Observe
that proportional functions operate smoothly, and
that brakes apply quickly after control is re-
leased.
11.While depressing foot switch, operate steer
switch to left and right. Observe that steering
wheels turn properly.
12.While depressing foot switch, turn function speed
control knob to desired setting, and operate
boom controls. Observe that boom operates
smoothly, and that upper boom, jib, turret rota-
tion, platform level, and platform rotation controls
operate proportionally in conjunction with func-
tion speed control knob. Observe that platform
maintains level when boom is elevated.
13.With the upper boom elevated one foot, operate
drive control handle. Observe that drive speed is
limited to creep (1/2 foot [.15m] per second).
Lower upper boom to stowed position.
14.Press the service horn button. Observe that
horn is audible.
DO NOT use a machine that is damaged or
malfunctioning. Tag and remove the unit
from service until it is repaired.
